Abstract
Unlike existing blueprint paper making process with medium glue application during pulping, the present invention makes blueprint paper by painting a layer of mixed paint of glue and whitening material on the surface of coping paper. The present invention features that a layer of pre-painted layer and a layer of sensitive material are painted successively onto the upper surface of wood-pulp coping paper and a back painting layer is painted onto the back surface.
Description
The blue printing paper and the manufacture craft that are made into copy paper that the present invention relates to belong to blueprint with paper and manufacture craft thereof, and actual is blue printing paper and the manufacture craft thereof that is made into copy paper.
During existing blue printing paper is produced, no matter be at a slow speed, middling speed, at a high speed, ultrahigh speed, dry method or wet method, blue line or black line all adopt special-purpose blueprint body paper, the blueprint body paper has only three home, the special manufacturer of four tame large-scale papermaking could produce, cost is very high, per about 10000 yuan/ton, production because of the blueprint body paper is to adopt the moderate applying glue to solve the resistance to penetration of blueprint body paper again, deflection, because prescription, technology, the places of origin of raw materials, the variation of additive, often bring quality problems, can not resist soaking into of diazol in the sensitization liquid, so all be unfavorable for the development of blue printing paper manufacturing enterprise on cost and the steady quality.
Purpose of the present invention is intended to improve above-mentioned deficiency, and a kind of technology that adopts copy paper to make blue printing paper and make blue printing paper of the preparation method of top sizing is provided.
In order to achieve the above object, the blue printing paper that copy paper is made, it comprises one deck whole wood pulp copy paper 1, be characterized in plane coating one deck precoated shet 2 on one deck whole wood pulp copy paper 1, on precoated shet 2, be coated with one deck photosensitive layer 3 again, at the back side of one deck whole wood pulp copy paper 1 coating one deck back coating 4.
In order to achieve the above object, the manufacture craft that copy paper is made blue printing paper is to realize like this, be characterized in one deck whole wood pulp copy paper 1 is adopted the method for top sizing---promptly with hauling machine traction one deck whole wood pulp copy paper 1, plane coating one deck 1.2-4g/m on one deck whole wood pulp copy paper 1
2The precoated shet 2 of the compo of glue and white material, glue is 1-3: 1.5-5 with the ratio of white material, the solid content of coating is 3-5%, and baking temperature is 80-120 ℃, and the coating speed of a motor vehicle is 15 meters-80 meters/minute, paper moisture content after the pre-coating is 4-7%, on precoated shet 2, be coated with one deck photosensitive layer 3 at last again, be coated with one deck back coating 4, draw with hauling machine at one deck whole wood pulp copy paper 1 back side, it is good to be rolled into barrier packaging with reel machine, promptly finishes.
Glue among the present invention mainly is to adopt acrylic resin, comprises polyhydroxy resin, polynary acrylic acid---ethene latex, alkyd resins etc. are any one of water and milk sizing material similarly, and white material package is drawn together silica, glutinous rice flour.
Photosensitive layer Main Ingredients and Appearance among the present invention is emulsion, coupling agent and auxiliary agent, belongs to prior art, and the Main Ingredients and Appearance of back coating is citric acid or the boric acid that water is added 0.5-1%, belongs to prior art.
The present invention adopts the moderate applying glue that the anti-sensitization liquid of increase soaks into to guarantee its absorbability and change over the coating that adopts surface coated one deck glue to mix with white material with the whole wood pulp copy paper at paper-making process former blue printing paper, whole wood pulp copy paper manufacture craft is simple like this, cost is low, the market price per ton is about 7300 yuan/ton, the rerum natura of whole wood pulp copy paper itself, satisfy engineering fully, building, the component of machine drawing use and preserve requirement, its whiteness, folding, smoothness is also consistent with the blueprint body paper, utilize surface coated, it is formed on copy paper surface a kind ofly can adsorb sensitization liquid, the film that sensitization liquid is soaked into again, make it reach the requirement of blueprint body paper, guarantee the coating requirement, the cost of blue printing paper has been reduced about 30%, and the present invention is at present a kind of reasonable blue printing paper and manufacture craft thereof of making of copy paper.
Description of drawings:
Accompanying drawing is made the structural representation of blue printing paper with copy paper for the present invention.
The explanation of accompanying drawing drawing:
1 one deck whole wood pulp copy paper, 2 precoated shets, 3 photosensitive layers, 4 back coatings.
In order to understand better and to implement, at length be described below below in conjunction with accompanying drawing:
